基于STM32的远程智能门禁终端的设计

摘要

This paper describes the design and implementation about how to control the CDMA module and RFID circuit by STM32.The hardware circuit of STM32 system has been designed and used to read the ID of the card to control the access state,and control the CDMA module to send the messages to the central control server.On the basis of the study about how to use the CDMA module and RC522 circuit,the design combined C language with the MDK development tool to write the CDMA module and RC522 circuit control program.%提介绍了通过STM32控制RFID电路和CDMA模块实现门禁终端的设计。硬件上设计了STM32系统电路，实现门禁终端RFID读卡并控制门禁状态，再通过控制CDMA模块实现门禁终端的信息发送到中央控制服务端。在研究使用CDMA模块和RFID电路的基础上，通过MDK开发工具结合C语言，编写控制程序。通过测试，满足智能门禁终端的多种功能。
